In this paper, a Microgrid (MG) test model based on the 14-busbar IEEE distribution system is proposed. This model can constitute an important research tool for the analysis of electrical grids in its transition to Smart Grids (SG). The benchmark is used as a base case for power flow analysis and quality variables related with SG and holds distributed resources. The proposed MG consists of DC and AC buses with different types of loads and distributed generation at two voltage levels. A complete model of this MG has been simulated using the MATLAB/Simulink environmental simulation platform. The proposed electrical system will provide a base case for other studies such as: reactive power compensation, stability and inertia analysis, reliability, demand response studies, hierarchical control, fault tolerant control, optimization and energy storage strategies.

The AC/DC hybrid microgrid (MG) has been widely promoted due to its high flexibility.The capability to operate in islanding mode is an appealing advantage of the MG, and also sets higher requirements for its control system. A droop control strategy is proposed on account of its distinguishing feature of automatic power sharing between distributed generations (DGs), but it introduces some drawbacks. Therefore, distributed cooperative secondary control is introduced as an improvement. In order to optimize the active power sharing in AC/DC hybrid microgrids, a number of cooperative control strategies have been proposed. However, most studies of AC/DC hybrid microgrids have mainly focused on the control of the bidirectional converter, ignoring the effects of secondary control within subnets, which may make a difference to the droop characteristic. This paper extends the cooperative control to AC/DC hybrid microgrids based on normalizing and synthesizing the droop equations, and proposes a global cooperative control scheme for AC/DC autonomous hybrid microgrids, realizing voltage restoration within AC and DC subnets as well as accurate global power sharing. Ultimately, the simulation results demonstrate that the proposed control scheme has a favorable performance in the test AC/DC hybrid system. Processes 2020, 8, 311 2 of 15can realize the global optimization of MG effectively, but the high communication cost and low reliability in complex systems limit its development [5]. The proposal of the distributed control scheme [6,7] can effectively reduce the scale of data transmission, so as to realize the global control of the complex system with low communication cost. Dehkordi et al. [8] proposed a complete hierarchical control strategy for AC microgrids and Chunxia Dou et al.[9] designed a superior distributed cooperative controller for DC microgrids with commendable dynamic performance. Fanghong Guo et al. [10] designed an efficient secondary controller with the superiority of less information transmission and demonstrated its excellent performance in DC microgrids. These above−mentioned studies only focused on one separate microgrid, while the control of hybrid microgrids needs to consider the coordination between AC and DC systems, which will be more complex [11]. Considering that the fluctuation of transmission power may pose a threat to the system stability, constructing an appropriate control scheme for a bidirectional AC/DC converter to determine a befitting power flow is of great significance. Yu Ji et al. and Wenyan Hu et al. [12,13] both proposed a control method for the bidirectional converter, while they expressed the imbalance of power sharing indirectly by the deviation of voltage and frequency rather than establish a direct relationship between the active power of AC and DC subnets, thus may bring about inaccurate power sharing with the participation of secondary control within subnets. Xialin Li et al. [14] analyzed the operation mode of the bidirectional converter in different scenarios roundly and gen...
